How to Change Yourself to Change Your Company

About The Book

An inspiring, practical book by Gui Loureiro, Regional CEO overseeing Walmex, Walmart Canada, and Walmart Chile, and his executive leadership coach Carlos Marin that shows how even the most successful leaders must be open to personal change in order to transform their company.

In the midst of a successful year, visionary CEO Gui Loureiro decided that Walmex—Walmart’s biggest division outside of the United States—needed to make massive changes to make the iconic company a more data-driven, customer-centric business that would be competitive in our digital economy. The stakes were high: no company the size of Walmex had ever attempted a transformation at such a magnitude of scale.

Reinventing the Leader is the turbulent story of how it happened that’s especially relevant in this age of globalization. Gui learns from Carlos that to change the company he must first transform his own leadership style. Written from the dual perspectives of a CEO and his leadership coach, this candid book provides an insightful blueprint for any organization’s success. Readers will learn:
  • The importance of connecting a transformation to a meaningful purpose
  • How any change brings risk but the biggest risk is not to change
  • The three crucial questions to ask team members to discern if they’re ready to contribute to a transformation
  • The need to tell the story of how the business impacts customers and customers impact the business
  • Why it’s necessary to listen attentively and embrace change independently of how successful you are.

Today’s leaders are expected to inspire by sharing a vision based on purpose, not just profits. Loureiro and Marin’s enlightening account of self-discovery and business reinvention defines a fresh new approach to leadership for the future.

Raves and Reviews

"Reinventing the Leader is among the most compelling business leadership books I’ve read in a long time. It’s exceedingly rare when both the dynamic CEO of a huge, iconic retail business and his seasoned executive coach tell all—in their own unvarnished words, and in the words of executives around them—about the dreams and fears they shared before, during, and after a major transformation of the business."
—John Alexander, President, Leadership Horizons, and former President and CEO, Center for Creative Leadership

“In his account of the digital transformation of Walmart Mexico and Central America (Walmex), Gui Loureiro has provided a textbook on leading through change. He not only reinvented the business while also delivering results, but he also reinvented himself as a new kind of leader . . . You won’t finish this book without sharing my enormous respect for what he accomplished—and how.”
—Doug McMillon, President and CEO, Walmart

“You’ll find no business jargon or easy aha moments in this remarkable book. Rather, it offers the at-times painfully honest story of a highly visible CEO with sufficient humility to realize that he needed to change before he could transform his company . . . Written with welcome clarity, this business narrative grabs you from the first page. Highly recommended for leaders and for coaches.”
—Sally Helgesen, Author, How Women Rise, Rising Together, and The Female Advantage

Reinventing the Leader is built on the rich experiences and remarkable introspections from two exceptional global business and thought leaders . . . It provides unique insights on how to lead change by transforming yourself to better serve all your stakeholders. It is truly one of the most inspiring leadership books I have read over the last 10 years.”
—Dr. Dominique Turpin, Emeritus Professor and former Dean and President, IMD

"Reinventing the Leader is a master class in leader growth and learning. It’s a unique, behind-the-scenes look into one leader’s efforts to transform a business and a coach’s reflections on leader reinvention . . . In the process, we see how changing organizations also means changing oneself."
—Jim Kouzes, Bestselling Coauthor, The Leadership Challenge, and a Fellow, Doerr Institute for New Leaders, Rice University
